Anthurium plant named ‘Rijn200310’

ABSTRACT

A new cultivar of  Anthurium  plant named ‘Rijn200310’ that is characterized by an upright and outwardly spreading habit, dark green leaves, free flowering, red spathes positioned above the foliage on strong erect scapes, long inflorescence life, large spathe size and white and yellow colored spadices.

Botanical classification: Anthurium andreanum.

Variety denomination: ‘Rijn200310’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofAnthurium plant botanically known as Anthurium andreanum and hereinafterreferred to by the cultivar name ‘Rijn200310’.

‘Rijn200310’ is a hybrid that originated from the hybridization of thefemale or seed parent a proprietary Anthurium identified as 9513 (notpatented) and the male or pollen parent a proprietary Anthuriumidentified as 9701 (not patented). The cultivar ‘Rijn200310’ wasselected by the inventor in February of 2003 as a single plant withinthe progeny of the stated cross in De Lier, The Netherlands.

Asexual reproduction by tissue culture of the new cultivar ‘Rijn200310’was first performed in May of 2003 in Melsen-Merelbeke, Belgium. Sincethat time, under careful observation, the unique characteristics of thenew cultivar have been uniform, stable and reproduced true to type insuccessive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the newAnthurium cultivar ‘Rijn200310’.

-   -   1. Anthurium ‘Rijn200310’ exhibits an upright and outwardly        spreading habit.    -   2. Anthurium ‘Rijn200310’ exhibits dark green leaves.    -   3. Anthurium ‘Rjin200310’ exhibits free flowering.    -   4. Anthurium ‘Rijn200310’ exhibits red spathes positioned above        the foliage on strong erect scapes.    -   5. Anthurim ‘Rijn200310’ exhibits long inflorescence life.    -   6. Anthurium ‘Rijn200310’ exhibits a large spathe size.    -   7. Anthurium ‘Rijn200310’ exhibits white and yellow colored        spadices.

The closest comparison cultivar is Anthurium ‘Rijn200002’ (notpatented). The new cultivar ‘Rijn200310’ is distinguishable from‘Rijn200002’ by the following characteristics:

-   -   1. ‘Rijn200310’ has smaller leaves than ‘Rijn200002’.    -   2. ‘Rijn200310’ has larger spathes than ‘Rijn200002’.

The new cultivar ‘Rijn200310’ is distinguishable from the male parentAnthurium 9701 in having thinner leaves and spathes and a spathe colorthat is less red.

The new cultivar ‘Rijn200310’ is distinguishable from the female parentAnthurium 9513 in having smaller leaves and spathes that are orange.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photograph illustrates the distinguishing traits ofAnthurium ‘Rijn200310’. The plant in the photograph shows an overallview of a 24 month old plant. The photograph was taken usingconventional techniques and although colors may appear different fromactual colors due to light reflectance it is as accurate as possible byconventional photographic techniques.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the new Anthurium cultivarnamed ‘Rijn200310’. Data was collected in De Lier, The Netherlands from24 month old greenhouse grown plants in 21 cm containers. The time ofyear was Summer and the average temperature was 23 degrees Centigradeduring the day and 21 degrees Centigrade at night. No photoperiodictreatments or growth retardants were used. Color determinations are inaccordance with The Royal Horticultural Society Chart 2001 edition,except where general color terms of ordinary dictionary significance areused. The growing requirements are similar to the species. ‘Rijn200310’has not been tested under all possible conditions and phenotypicdifferences may be observed with variations in environmental, climatic,and cultural conditions, however, without any variance in genotype.
